As for Central Picture in 2 x 6 Year Planner

I have installed SC v5.3.1417 and I am trying to use Year Planners- 2 x 6 Central Picture but I am unable to use one central picture as depicted in the template. Granted that one can select 0, 1, 2, 3, or even 4 pics, BUT if I opt for just one pic, I cannot centralise it as per the image on the template.

Seondly, there is a sub-menu 'Promotional Pictures (Logos)' under the "Promotion Menu". Even though this is in plural form, I am unable to add more than one promotional logo.
